The carbon footprint for Norfolk is about to shrink, with the introduction of a ground-breaking system using biofuel for heating. The county council is taking part in a 12-month trial with the University of East Anglia and the oil industry, using mixes of biodiesel and kerosene to heat seven schools in the region, Gressinghall Museum, and private homes. It is the first time the fuel mixes have been used in existing heating systems. Ian Roe, the county council's business co-ordinator for environment and waste, said: ‘The trial is to look at how effective it is to use a biofuel mix in heating.' The biodiesel, made from used vegetable and animal fat, produces less carbon dioxide than conventional fuel when burned. The system is already up and running at one school in the county, as well as a number of private households. Over the next few months, it will be introduced into the remaining schools and museum, and results are expected early next year.
